That's a pretty awesome list anyway, but that's just the basic shape! Apart from the Skeletons, Cyclops and Medieval Knights, which can't look any more epic, all the monsters have at least 4 skins to choose from, in fact, TROLLS HAVE 20 SKINS! Then, if that's not enough, choose their stats! It even says the recommended level for fighting them! Want a weak, sandy-looking Troll? Done. A battle-hardened Orc mercenary? Done.
AND THEN, as if all of that wasn't enough, choose when and where they appear. Never heard of a green Yeti that beams down from space, yet dies in a single punch? Well you can make one! Happy monster-slaying everyone! And well done for everyone who had some part in making the game.
